"Sober" is in line with Lovato's tendency to be very open with her fans and the world about her struggles with drug and alcohol addiction, which is an important conversation to be having on the national stage.

Here are 6 times other celebrities have been brutally honest about their struggles in their own recovery journeys, including relapsing.

Ever since Demi Lovato revealed that she had been struggling with cocaine and alcohol addiction, she's been extremely candid and open with her fans, and the world, about her own personal journey in sobriety. Through autobiographical songs like "Skyscraper," and in documentaries "Demi Lovato: Stay Strong" and "Demi Lovato: Simply Complicated," Lovato has shed some light on the taboo subjects of addiction and mental health.

Which is why it was heartbreaking when she released the newest single from her upcoming seventh album on June 21, entitled "Sober," where she appeared to reveal that she had relapsed.

But she wouldn't be alone in relapsing. According to the National Institute on Drug Abuse, 40 to 60% of all drug addicts will relapse at some point, and Dr. Scott Krakower, assistant unit chief of psychiatry at Zucker Hillside Hospital told the New York Daily News that that number goes up to 80% when dealing with opioid addiction.

Hopefully, Lovato's candor about the ups and downs of her own recovery journey will continue to increase awareness about this disease. And she is not alone — here are six other celebrities who have been open about their struggles with addiction, recovery, and relapsing.

Kelly Osbourne attended rehab three times before getting clean for good.

She first attended the Promises Treatment Center in Malibu, California, in 2004 after being caught with prescription drugs, but Osbourne called it "too comfortable" and likened it to "vacation without a bar."

Osbourne was back in rehab again by 2005, but was unable to stay clean — when she moved to Los Angeles in 2009, it triggered a relapse. "I couldn't see into tomorrow. I was using anything to make me sleep through the day. I got really into smoking pot," she told People, "It's so embarrassing, the number of times I've thrown myself down the stairs to try and hurt myself to get pills."

But her third stay in rehab is what stuck. "This is a disease. I was born with it. I'll die with it," said Osbourne, "I just want to be happy. Anything is better than the way it was."

Kelly Osbourne's famous father Ozzy Osbourne has also dealt with addiction and relapsing, sharing on Facebook in 2013 that he was "44 days sober."

In 2013, the rock star revealed on Facebook that he had begun drinking and using drugs again after an unspecified stretch of sobriety. He wrote, "For the last year and a half I have been drinking and taking drugs. I was in a very dark place and was an a--hole to the people I love most, my family. However, I am happy to say that I am now 44 days sober."

Five years later, Osbourne is still clean and sober, though he has been open about the daily struggle. He told Goldmine Magazine, "I am not really happy being sober, but I don't want to get drunk."

"The Hills" and "Laguna Beach" star Jason Wahler admitted to relapsing in April 2018 after four years of sobriety on Instagram, writing "At first I was full of shame and guilt, but I am learning to forgive and move forward."

Wahler has been very open with the public about his struggles with substance abuse — much of it was recorded on "The Hills" during his relationship with Lauren Conrad. The reality star even founded his own sober living facility, called Widespread Recovery.

"However, I became complacent and I was blindsided," he continued. "I am beyond embarrassed. At first, I was full of shame and guilt, but I am learning to forgive and move forward. I can only hope my pain will be someone else's gain and I will continue to live one day at a time. The truth is this: I relapsed, I surrendered and I am getting help. We are each a link in a chain and together we are stronger. Surrender. Don't be afraid to start over. You are worth it."

In an interview with Rolling Stone, the country star called his wife his salvation. Before she staged an intervention for him in 2006, Urban had been in rehab twice before only to relapse.

But before he met his wife, Urban went through rough times and struggled with dark thoughts. He told Rolling Stone, "I remember thinking, 'I'm probably not going to make it until tomorrow.' And then I thought, 'F--- it. I really don't care. It'll be a relief to not have to. I'll take an Ambien and at some point I'll pass.'"

"I caused the implosion of my fresh marriage," he said. "It survived, but it's a miracle it did. I was spiritually awoken with her. I use the expression 'I was born into her,' and that's how I feel. And for the first time in my life, I could shake off the shackles of addiction."

Macklemore said that the pressure of fame contributed to his relapse — he "just wanted to escape."

He admitted to hiding his backslide, and even hiding sleeping pills in his shoes. He also called himself "sneaky" and "deceitful."

"I'm rolling around like a 15-year-old trying not to get caught smoking weed in my car," he said, "Straight up, driving all around here, like I was 15 years ago. Same s---. I felt so dumb. I felt like I'm just wasting time. What am I escaping here?"

Macklemore decided to truly commit to recovery again once he found out his girlfriend was pregnant with their first child, saying, "Since I heard that Tricia was pregnant, I was like, I need to grow up right now."

Eminem has been extremely frank about his battles with drug abuse, naming two of his albums after terms associated with addiction: "Relapse" and "Recovery."

Post-rehab, he ended up in the hospital after an overdose, and was clean for two weeks before relapsing again. After a near-brush with overdosing again, he committed to getting clean, and now is able to reflect on addiction and his own addictive tendencies.

"I wish I was wired like a regular person and could go have a f----n' drink. But that's the biggest thing about addiction: When you realize that you cannot — for f---'s sake, you can not — f--- around with nothing ever again," he continued, "I never understood when people would say it's a disease. Like, 'Stop it, d---head. It's not a disease!' But I finally realized, F---, man — it really is."

Lovato tweeted in March 2018 that she was celebrating six years of sobriety. But in June 2018, Lovato released a new song called "Sober" that discusses a relapse. When she released the song, she wrote "My truth" on Twitter, leading some fans to believe she's referring to a recent relapse.

The ballad frankly states that she had begun drinking again, with lyrics like "Mama, I'm so sorry I'm not sober anymore / And daddy please forgive me for the drinks spilled on the floor," and "And I'm sorry for the fans I lost who watched me fall again / I wanna be a role model, but I'm only human."

"waking up listening to @ddlovato "sober". Im proud of you for having the guts to reveal your truth to the world again. NOT. EASY. Im here for you friend! (you know this) I pray you'll choose recovery again. All of us who love you only want to see you happy and healthy"
